Embodiment Construction

[0025] figure 1 A printing press 1 is shown which has an offset printing unit and a flexographic printing unit as varnishing unit 48 . The printing press is a sheet printing press with a feeder and a delivery not shown.

[0026] figure 2 It is shown that the coating unit 48 has a plate cylinder 2 and a plate changer 5 for changing the printing plates 4 . Plate 4 is a flexographic plate for spot varnishes. During printing operation, a roller 42, which is both an application roller and an anilox roller, rolls on the printing plate 4 .

[0027] image 3 It is shown that the plate changer 5 has a plate guide 14 and a plate well 5 which extends vertically. The plate guide 14 is mounted in the hinge 13 and is foldable. The transport slide 6 is mounted displaceably in a printing plate guide 14 . The printing plate guide 14 is pivoted about the articulation 13 in order to adjust the printing plate guide 14 into the feeding position 46 (see FIG. 4 ). The printing plate guide 1...
